Which exhaust brake would you recommend

I had a pack brake pxrb on my 03 ram it was ok at best I wasn't wild about the way it came on the converter would unlock if you were to downshift or turn the O/D off and you would have to rev up the motor to re lock the converter.I hated the way it made the truck shift with the pack brake turned on I think it would shift with the converter locked up. In my opinion it was bass ackwards. You should check out the pack brake pxrb that ats does the electronics for on their website. I have also heard they (pack brake) have one out that hooks to the heads like a real jake don't have any more info.
